Federalism: The division of power between the national government and state governments. It allows states to have some autonomy in governing themselves while still being part of a larger federal system.
Devolution: The transfer of powers from a central government to regional or local governments. It can grant more authority and decision-making power to states, allowing them greater freedom for experimentation.
Dual federalism: A constitutional interpretation that emphasizes a strict separation between federal and state powers, limiting the role of the national government and giving states more independence in policy-making.
